You know that fold of fabric created when you snap down the front of a
one size cloth nappy to adjust its size? Have you ever wondered whether
there's a 'right' direction to fold it?

Love this little video from GroVia demonstrating that folding it up is generally better than down - it
creates less bulk and a better fit across the thighs. And yes, this is the case
for most nappies with an adjustable rise.
